Attention: 

If the BX-GM6 loses power for any reason, the following steps will need 

to be performed again.

•  Turn the key to ignition.

•  The L.E.D. in the interface will blink rapidly, and the relay attached to it will click fast.

Note:

The L.E.D. is located next to the potentiometer and can only be seen while active.

•  Once the L.E.D. and relay stop, the interface will flash slowly up to 15 times 

indicating which radio it “sees” is connected to it. Pay close attention as to how 

many slow flashes there are. This will help in troubleshooting, if need be.

•  The radio will then turn off and the L.E.D. will light up solid. After the L.E.D. goes 

out, the radio will come back on.

Note:

This process can take up to a minute to complete.

•  Immediately after the L.E.D. goes out, the following buttons on the steering 

wheel must be pressed in the exact sequence as shown. For each button press, 

the L.E.D. will light up momentarily:

  •  Volume Up

  •  Seek Up

  •  Volume Up

  •  PTT (OnStar)

  •  Volume Up

•  The L.E.D. will light up solid after the last Volume Up button has been pressed, 

indicating programming has ended.

•  Press all the buttons to ensure they are working as intended.
•  Cycle the ignition and test again.

Notes:  

PTT (OnStar) when pressed will Mute/Attenuate the radio.
PTT (OnStar) when pressed and held for 2 seconds will activate OnStar.

Adjusting the BX-GM6

OnStar level adjustment:

•  Press the OnStar button to activate it.
•  While OnStar is speaking, press the “Volume-Up” or “Volume-Down” buttons on 

the steering wheel to raise or lower the OnStar level.

•  If the vehicle does not come equipped with steering wheel controls, find the 

Black/Yellow

 wire on the 22-pin harness.

• 

While OnStar is speaking, tap the 

Black/Yellow

 wire to ground. Once the OnStar level 

is set, it will stay at that level until the 

Black/Yellow

 wire is tapped to ground again.
